System of Equations:

let x be the cost of a taco

let y be the cost of a burrito

7x + 3y = 22

3x + y = 8

The cost of a taco is $1

The cost of a burrito is $5

Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)

Answers:

Equations: 7x+3y=22

                  3x+y=8

The cost of tacos is $1 and the cost of burrito is $ 5.

Step-by-step explanation:

Let the cost of tacos be x and the cost of burrito be y.

Equations: 7x+3y=22

                  3x+y=8

3x+y=8, y=8-3x

sub  y=8-3x into 7x+3y=22, 7x+3(8-3x)=22

                                                          -2x=-2

                                                              x=1

sub x=1 into 3x+y=8, 3(1)+y=8

                                        y=5

∴The cost of tacos is $1 and the cost of burrito is $5.
